How I fixed a Sansa Clip+ version 1 that was stuck on the “Refreshing media” screen:
- Plug into a windows PC via USB
- Delete all files from the drive root of the Clip+
- Paste the driver file clppa.bin into the drive root of the Clip+
- Eject the Clip+ from the Windows PC
This made the device completely wipe clean and working again to play music.
